TRIP FR GRAIN BNDERS.

Application filed November 6, 1920. Serial No. 422,252.

To allan/om t may concern:

Be it lrnorvnthat l, llrcrrfinn P; Sarnen, a citizen oi the `United States, residing at Lincoln, in the county et Logan and State e oli' Illinois`v have invented certain new and useful Improvements in rlrips for Grain Binders, of which the following is a specication.

' The present invention consists ot a trip to for grain bindersI and is designed especially for use on standard types of binders to trip the bundle carrier and automatically return the latter atter the bundles have been de posited.

An object oi" this invention is to provide a trip mechanism oi simple construction which may be quickly and conveniently associated with the stub tongue of the binder and is detachably connected thereto, where- 2o by the mechanism may be removed when the binder is not in operation.

rlhe above and other objects olf this invention will be in part desc ibed and in part understood from the following description of the present preferred embodiment of the invention talren in connection with the accompanying drawings, wherein:

F ig. 1, is a top plan view of the device constructed in accordance with my inven- 30 tion.

F ig. 2, is a side elevational view thereof.

Figure 3, is a transverse sectional view taken on the line 3-3 of F ig. 2, and looking in the direction of the arrow, and

Fig. l, is a fragmentary perspective view of a grain binder bundle carrier showing the manner ot connecting' my improved trip thereto.

ln the drawings, a stub tongue of a binder is provided as indicated at l and .is equipped at vone end with conventional means 5 for connectineV the tongue to the binder. fr

brace member 6 also oit standard construction is mounted on the tongue and adapted for engagement with the binder in a Well lrnovvn manner.

My invention per se consists especially of a rocker bar 7 which is pivoted approximately midway its ends on the bottom face of the stub tongue and has the opposite ends thereof extended beyond the lateral margin ot' the tongue and provided at one end With a series of openings 8, one of which is adapted for engagement with one end of a trip rod 9, the opposite end of the latter being engaged with the bundle carrier. The rocker bar is operated by a hic-lr rod 10, one end of the latter being engageable in any one of a plurality of openings 11 While the opposite end is vertically offset to lie appreciably below the lowerv tace of the tongue 4land has ,its tree terminal connected to one end of a lever 12. The lever 12 constitutes the operating lever and is pivoted, as indicated at 13, to one side ot the stub tongue, extends above the latter for a short dist-ance and is then bent obliquely. The oblique part of the lever terminates at its upper end in a substantially horizontal portion 14, the terminal of which latter is twisted to provide a handle 15. A series of `openings 16 are formed in the horizontal portion of said lever and are adapted for engagement with an extension lever (not shown), so that the lever may be lengthened or shortened to suit the desire of the operator of the machine. The operating lever will preferably lie adjacent the operators seat so as to be convenientlymanipulated by the operator when seated.

rllhe. opposite end of the rocker bar 7 to the one with which the trip rod 9 is connected is likewise provided with a series of openings 17, any one of which is adapted to receive one end of a return sprin'g 18, the opposite end of the latter being engageable with any one of a plurality of chain linlrs 19 which are carried by an ear 20 which is mounted upon the side of the stub tongue 4t. The return spring is adapted to retract the rocker bar after the latter has been moved through operation of the lever 12 for actuating the bundle carrier. By changing the spring in the openings 17 the leverage of the bar 17 will be correspondingly changed. Also the tension of the spring maybe varied by an adjustment of the linlrs 19 in an obvious manner.

Mounted upon the outer face of the lever 12, directly above the axis of the latter, is a linger 21 Which curves rearwardly to- Wards the rocker bar 7 and is in engagement with one end of a spring 22, the opposite end of the latter being adapted for engagement with any one oi a plurality oit chain links 28, the latter being carried by an apertured ear 24 which is carried by the upper tace of the tongue il. The function of the spring 22 is to return the lever 12 to a normal position after operation or". the latter, this spring coadoing` with the spring 18 so as to quickly and accurately reset the CIK mechanism automatically after the said mechanism has been manually operated. The tension of the spring 22 is adjusted by changing the links With which it is connected. A

lVlien in position on a Standard type of binder the operating lever 12 will be aocessible to the operator located on the seat of the binder. Movement of said lever downwardly 1will cause the kick rod l0 to be moved rearwardly, thereby rocking the bar 17 and imparting` movement to the trip rod 9. Ii" the rod 9 be placed connection with the bundle carrier of a binder. the bundle carrier Will be tripped7 by action of the rod 9, to thereby deposit the bundle on the round. Just as soon as pressure is released trom the lever l2 the springs 1S and 22 Will contract, thereby returning the bar 7 and lever 12 to their normal positions. This Will permit the binder to be completely manipulated by one man and will eliminate the necessity of using an operator solely for the purpose of tripping the bundle carrier as is very often the case et the present time.

Various changes be made by me in this device especially in the proportion and arrangement of parts Without departing` from the spirit and scope of my invention.`

Vhat is claimed is:

A trip attachment for the bundle carrier of binders including a rock bar mounted upon the binder tongue and equipped with a rod which engages the bundle carrier to trip the latter, a levermovably mounted on said tongue and in connection with said bar to operate the latter for trippingf the carrier,` and springs connected with said tongue and with said bar and lever to automatically return said bar and lever to a normal position as soon as pressure is released from the latter.
